On behalf of my colleague: =20 =93I am doing a project which is relevant to gameport interface. I face the problem on reading analog input. One end of the potentiometer is connected to +5V pin and the center pin is connected to analog pin of the gameport. I do not use any joystick to test my gameport. I connect the potentiometer to the gameport directly. However I don=92t know how = to read the value of analog input by using program written in Visual Basic. Besides that, I have download a joystick test program called Jcenter.exe from CH product. I am not really understand how it works. Does anyone know about it or any source code that I can refer to? =93 =20 =20 regards, Donny Tan -- http://www.piclist.com#nomail Going offline?
